Title: Electronic switch circuit
Inventor: YONEYAMA TOSHIKATSU
IPC: H03K17/60
Filed: 1985-05-02
Abstract: PURPOSE:To attain the electronic switch circuit with small on-resistance by means of a transistor (TR) having a large on-resistance by constituting an amplifier circuit with an emitter follower circuit provided with a variable impedance function and an impedance converting function as a negative feedback amplifier circuit. CONSTITUTION:The 1st TR 3 and the 1st constant current source 5 constitute a common emitter amplifier and a signal is fed back negatively from a collector of the TR 3 being an output terminal to a base of the TR 3 being an input terminal through the emitter follower circuit. Since the maximum signal current flowing to the input terminal 1 is equal to a current I flowing to the 2nd constant current source 6, the driving capabiity of the electronic switch circuit is varied by using the current I flowing to the 2nd constant current source 6. When the 1st and 2nd switches 7, 8 are turned off, the 1st and 2nd TRs 3, 4 are also turned off, the input impedance viewed from the input terminal 1 is infinite and in the open state. Thus, even when a TR having a large ON- resistance is used, the performance of grounding or open function is improved and a sufficient switch characteristic is obtained.

Title: Voltage control multivibrator
Inventor: ASATANI KOUICHI
IPC: H03K3/282
Filed: 1978-08-02
Abstract: PURPOSE:To realize the multivibrator circuit having good linearity in input voltage versus output frequency characteristics, by providing the FET constant current circuit with the emitter of the transistor. CONSTITUTION:The constant current circuit is constituted with FET 8 and 9, and the gate voltage of FET is given from the operational amplifiers 10 and 11. The non-inverting input of the operational amplifier is kept at the control voltage Vi and the feedback current ib flows from the source resistors 12, 13(resistance value R1) to the inverting input of the operational amplifier. In this case, the current is constant, j0=Vi/R1+jb. Normally, in case of operational amplifier, jb is several nA to several muA. Since this value is smaller in several orders than that of the bipolar transistor, j0=Vi/R1 can be regarded. That is, the linearity in input voltage versus output current is very excellent, and accordingly, the linearity in input voltage versus output frequency can be obtained from the relation of oscillation frequency f i0/C.

Title: X-ray aligner
Inventor: IGUCHI KATSUJI
IPC: G03F9/00
Filed: 1987-04-16
Abstract: PURPOSE:To make a wafer expand and contract against an X-ray mask and control the multiplification factor ratio of the X-ray mask to the wafer and obtain an X-ray aligner independent from the fluctuation of a gap between the wafer and the mask by a method wherein the temperature of the X-ray mask and the temperature of the wafer are varied by utilizing difference in thermal expansion coefficient between the X-ray mask and the wafer. CONSTITUTION:An optical signal 31 outputted from an optical unit for a measurement of relative position of a mask and a wafer in a exposure equipment 30 is converted into an electrical output by a detector 32 and, by a position discrepancy value calculation program 33, a gap (g) between the mask and the wafer and position discrepancies x1, x2, x3 and y4 in a square in an exposure field are calculated and the expansion and contraction coefficient DELTAM of the mask to the wafer is calculated. A temperature control program 38 calculates a temperature necessary to correct the multiplification factor and outputs the instruction for temperature change to a temperature controller 39 of circulating water 40 for an X-ray mask holder and a wafer temperature control stage to correct DELTAM. By repeating the above-mentioned procedure with suitable cycle time, the mask and the wafer can be aligned with each other highly accurately.

Title: Signal detecting circuit
Inventor: HAYASHI HIDEAKI
IPC: G11B19/28
Filed: 1982-06-01
Abstract: PURPOSE:To control the level of a data reading comparator, by using a difference data between the maximum data of inverse intervals which continue with polarities reverse to each other and the setection output of the data intervals of polarities reverse to each other. CONSTITUTION:For the output of a logical circuit 9b, a pulse output is delivered when A=B or A B is satisfied for the comparison output between data A and B. Thus latching circuits 11 and 12 are gated, and the data of latching circuits 6 and 7 are shifted to the circuits 11 and 12. The circuits 11 and 12 can have high resistance to the jitter, etc. of a signal by extracting the data A and B by means of a window compartor when A B is satisfied instead of A=B and after these circuits 11 and 12 latch the data corresponding to the plus and minus polarity intervals of a synchronizing signal. The outputs of the circuits 11 and 12 are applied to a subtraction circuit 13 to obtain the difference of data. This difference of data is converted into an analog form through a D/A converting circuit 14 and applied to an input terminal in the form of the reference voltage (v) of a comparator 1.

IPC: G11B3/08
Filed: 1982-06-01
Abstract: PURPOSE:To decrease the number of component parts and to facilitate an easy assembly, by using a coupling plate having a monolithic structure of polymer materials to connect a supporting member which moves up and down an arm and an operation means. CONSTITUTION:A coupling plate 9 having a monolithic structure of polymer materials contains a pair of coupling bars 9a and 9b, a detaining bar 9c which detains a coil spring 8 and a cylindrical rib 9d. The bar 9b which is set under a projection 4a of a cam 4 has a rather small thickness. An end of a revolving shaft 6b of a speed control parts 6 is pressed into the center of the rib 9d of the plate 9. Then the plate 9 is slowly turned at a fixed speed owing to the resistance of viscosity of the viscious oil applied around the shaft 6b. The spring 8 is extended and contracted with a switching action of a queuing lever. Thus the plate 9 is turned, and accordingly the cam 4 moves up and down. As a result, a pickup arm is moved up and down.
